Essay on Global Warming

The earth is constantly undergoing changes. This ranges from tectonic activity to atmospheric and climate changes. The most recent change that we have noticed, is the increase in temperature. Some believe that this increase is the result of human activity. However, this is not the case. The increased temperatures are within the normal tolerances from the past few thousand years (Robinson, Robinson, & Soon, 2008). This and other changes to the atmosphere have been going on for millions of years. Global warming is not our fault because it is a natural occurring phenomenon.

Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009,

We all see the weather change from day to day and it is just a normal occurrence. Seasons change from warm to cold and we all just go about our business. But what most people don’t see change is the climate. Climate changes over a long period of time and it has shown a warming trend in the past few decades. Many people attribute this warming trend to the alarming rate that humans are burning fossil fuels and pumping Co2 into the atmosphere, however some people think that climate change is merely a myth or that global temperatures have always risen and fallen during Earth’s lifetime.

The Earth's climate has changed throughout history. According to the findings of National Aeronautics and Space Administration (NASA), the change of the earth’s climate has evolved through time. The global sea level rose about eight inches in the last century; the planet's average surface temperature has risen about 2.0 degrees Fahrenheit since the last 19th century; the oceans have absorbed much of this increased heat of 0.302 degrees Fahrenheit since 1969; the increasing number of record high temperature and intense rainfall events since 1950; and the overall increase of ocean acidification by about 30 percent. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century. There is no question that increased levels of greenhouse gases cause the Earth to warm in response.

A very visible effect of climate change has been the steady melting of sea ice and glaciers, especially in the Arctic.The IPCC has projected that the Arctic could be virtually free of summer sea ice by 2070, and more recent studies project this could occur several decades sooner. If this were to happen, and we continue using fossil fuels instead of more environment safe energy sources such as hydroelectric power or wind power, parts of Miami and New Orleans would become nearly inhospitable. The melting of land-based ice,

There has been a continuous change in the Earth’s climate throughout history (National Aeronautics and Space Administration (NASA), 2016). According to NASA, there have been seven cycles of glacial advance and retreat in the last 650,000 years (National Aeronautics and Space Administration (NASA), 2016). The last ice age was about 7000 years old and marks the beginning of the modern climate era and human civilization (National Aeronautics and Space Administration (NASA), 2016). These changes have been attributed to small variations in the Earth’s orbit that changes the amount of solar energy received by the Earth (National Aeronautics and Space Administration (NASA), 2016). Orbiting satellites and other technological advances such as telescopes,

Evidence indicates, Earth’s natural climate has a history of dramatic changes from warmer and cooler periods that can last for a few centuries. Mankind geologically speaking lives in a time period of intense climate change, and over the past million years we have experienced a dozen or so major glaciations, with the greatest occurring around 650,000 years ago, long before the Industrial Revolution, The Ice Age. This cooling period in Earth’s climate lasted for somewhere around 50,000 years and included the extreme buildup of ice that covered major regions, such as the Midwest, Canada, Germany, and several smaller regions. During this time the sea level had dropped by approximately 400 feet and the overall global temperature dropped nearly 9

There is noticeable change in the climate of the earth through the passes of the time due to natural factor as well as the human activities by the production of the excessive amount of the gases responsible for trapping the energy. The change in the earth climate is influence by human civilization by the production of the different greenhouse gases like carbon dioxide, water vapor, and sulfur dioxide gases. Its true that the temperature of the earth is increasing. The phenomenon of the global warming can be seen as the temperature of the earth surface is increasing throughout the world. There are many evidences that shows that the earth climate system is warming. Different studies done at different period of time shows that the temperature

Climate change has been in the news for years. Earth's average temperature has risen by 1.4°F (0.8 degree Celsius) over the past century, and is projected to rise another 2 to 11.5°F (1.1-6.6 degree Celsius) over the next hundred years. The main cause of climate change is due to the

Climate change is defined as “a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.” Climate change has happened as a cycle throughout history, with ice ages occurring, and then warming. The earth naturally warms and cools, but due to the burning of fossil fuels the rate is growing exponentially.

The first argument many individuals would make against global warming is that the current climate changes are simply part of the patterns seen in the Earth’s geological history. Global warming would easily be proven as a result of human activity if the Earth’s temperature had been stable for the majority of its geological history. However, for over two million years, during the Ice Ages, the Earth’s temperature has increased and decreased continuously. The Earth’s temperature rose from very cold temperatures that formed glaciers to very warm temperatures that melted glaciers and vice versa. There is a total of five major ice ages that took place throughout the Earth’s history: the Huronian, Cryogenian, Andean-Saharan, Karoo and Quaternary. Moreover, scientists at the Earth Observatory of NASA, have created a record of the Earth’s temperature over the past 800,000 years. This paleoclimate record shows the Earth’s many ice ages as well as years in which the Earth’s temperature was warmer than that of current climate changes (Ichoku). Thus, the current climate changes occurring all over the world are

Climate change has been a problem for many years. Usually, people tend to think that this problem has been developed in the last decades, but that is absolutely false. Climate change is originate from more than 5,000 years ago when the first humans beings started clearing land by cutting and burning forest according to the Professor of Environmental Science William F. Ruddiman. This happens because when forests are burn, carbon dioxide goes into the atmosphere thus causing damage to the environment. Clearly, the earth has experienced climate change in the past, but the current climatic warming is occurring much more rapidly than past warming events. The effects of climate change are affecting our ecosystems considerably. Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. The effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.

There are various consequences that may arise if significant global warming begins to take effect. Some scientists believe that over the next 50 years, global temperatures could rise by as much as 1.5-4.5 degrees Celsius worldwide (Climate Change, 1997). Many speculate that this increase in temperatures could produce profound, if not devastating effects to our environment and ourselves. Already, many scientists are attributing some of the severe weather around the world such as hurricanes, floods, and droughts to global warming (Bernard, 1993). The high-latitude regions are likely to have the largest temperature change, while regions such as the North American Great Plains are predicted to feel a large decrease in precipitation (Climate Change, 1997). In regions with a lowered precipitation rate, agriculture would suffer, potentially causing severe economic and food shortage problems. Numerous species of plants and animals could also suffer, causing permanent damage to ecosystems and biodiversity. It is also thought that because of

The history of climate on the earth is developed with immense changes that have occured way too quickly within decades and even the past few years. We know climate change “refers to a broad range of global phenomena created predominately by burning fossil fuels , which add heat trapping gases to Earth’s atmosphere” (NASA). These include long-term changes in the global distribution of weather patterns. The changes in these conditions hugely affect not just us, but the environment as well. A major effect from climate change is known as global warming. According to NASA global warming is the “upward temperature trend across the entire Earth since the early 20th century...due to increase in fossil fuel emissions since the industrial revolution” (NASA). Concerns for climate change as the outcome becomes more and more vivid.
